Microfibrous entrapped sorbents are best applied to processes where there is a need for high-contact efficiency removal of critical contaminants.
Polishing Sorbents and Composite Beds
An ideal application for microfibrous entrapped sorbents (MFES) is in composite beds with enhanced breakthrough times for multi-log contaminant removal. Composite beds are composed of a packed sorbent bed followed by an MFES polishing sorbent. This configuration enables the best characteristics of the packed bed (high capacity) and the MFES (high sorption efficiency and sorbent utilization) to be maximized to significanly enhance breakthrough time without significant changes in bed size or pressure drop. The effectiveness of this approach as already been demonstrated for gas-phase desulfurization.
Active Filtration Processes
The combination of low pressure drop and high efficiency contaminant removal also makes MFESs ideal for active filtration processes where there is a need for simultaneous particulate and molecular contaminant removal or high-efficiency, low pressure drop molecular contaminant removal.
